Audio AMP

Nothing but Audio amplifier box.Except for the bottom , that is 3mm thick aluminum plate, all made of wood.The front panel is a horse chestnut, side and top plate are birds eye maple.A knob and inlay are African block wood.

The contents are Raspberry Pi 3 with Pifi DAC, a digital amplifier and two switching regulators.So far the heat generated most comes from the CPU of Raspberry Pi3.
But the audio program running on the CPU consumes only 10-20% of CPU power. I believe the heat effect against the woods is minimal.
